What size valve is a Ford FE?


The Ford FE engine, a staple in American automotive history, is known for its robust performance and versatility. Whether you're a classic car enthusiast or a mechanic, understanding the specifications of the FE engine, particularly its valve sizes, is crucial for maintenance and performance upgrades. In this article, we will delve into the details of the valve sizes used in Ford FE engines and their implications for performance.


Valve Sizes in Ford FE Engines


The Ford FE engine family, which includes various models produced from the late 1950s to the early 1970s, typically features the following valve sizes:



  • Intake Valve Size: 2.0 inches (51 mm) for standard models, with some high-performance variants featuring larger valves up to 2.09 inches (53 mm).

  • Exhaust Valve Size: 1.5 inches (38 mm) for standard models, with high-performance versions having exhaust valves up to 1.73 inches (44 mm).


These valve sizes are significant as they directly influence the engine's airflow, efficiency, and overall performance. Larger valves can improve airflow, which is essential for high-performance applications, while standard sizes are adequate for everyday driving needs.


Performance Implications of Valve Size


Choosing the right valve size for your Ford FE engine can have a profound impact on its performance. Here are some considerations:



  • Airflow Efficiency: Larger valves can enhance airflow, allowing for better combustion and increased power output.

  • Engine Tuning: When modifying an FE engine for performance, selecting the appropriate valve size is crucial for achieving the desired horsepower and torque.

  • Compatibility: Ensure that any changes to valve sizes are compatible with the engine's cylinder heads and overall design to avoid performance issues.


Understanding these implications can help you make informed decisions when upgrading or maintaining your Ford FE engine, ensuring optimal performance and longevity.


Conclusion


In summary, the Ford FE engine typically features intake valves of 2.0 inches and exhaust valves of 1.5 inches, with variations for high-performance models. Knowing these specifications is essential for anyone involved in the maintenance or modification of these classic engines. Whether you're restoring a vintage vehicle or enhancing performance, the right valve size can make all the difference.


Frequently Asked Questions

What is the valve clearance of a Ford?


So just set your valve clearance to 0.015 and you will have a good running, quiet engine. Sure every valve will have a different lift, duration and valve timing but it will be minor and the engine will run well.



What is the standard car valve size?


There are basically two sizes of tyre valves in use; 8v1 and 12v1. A 8v1 Tyre Valve is the standard Schrader car tyre valve size found on the majority of tyre valves. The nominal bore on a 8v1 Tyre Valve Connector approximately 8mm in diameter.



How do I know what size valve I need?


A general practice to determine the correct valve size is to use the equation Q = Cv√(ΔP/G), where Q is the capacity in gallons per minute, Cv is the valve flow coefficient, ΔP is the pressure differential in pound per square inch, and G is the specific gravity of the fluid.



What is the correct valve clearance?


Opinions may vary between piston and valve manufacturers, but a popular consensus is a minimum clearance of . 080-inch for the intake and . 100-inch for the exhaust. The exhaust valve expands more due to heat from combustion, and therefore needs additional clearance.



How much horsepower did the Ford 406 have?


385 hp
There were 3 variations. Single 4 barrel, 11.4 to 1 compression, 385 hp.

What does 427 FE mean?


FE stands for Ford Edsel. It's a series of skirted block engines produced from 1958 to 1976, with a 10.17” deck height and 4.630” bore centers. Displacements were 332, 352, 360, 361 (really an Edsel version 360), 390, 406, 410, 427, and 428 cubic inches.

What is the difference between a 406 and a 427 Ford?


Though mid-year 406s and all 427s were cross-bolted main blocks, both were different castings entirely. In fact, the 427 block is a completely different animal because it sports huge 4.23-inch bores, unlike any of its FE siblings, using the 390 and 406's 3.78-inch stroke.
